APPARATUS FOR ELEVATING LIQUID.

Patented June 4, 1918.

Application filed February 17, 1917. Serial No. 149,240.

To all whoin it may concern:

Be it known that I, JAMES A. MACKENZIE,

aicitizen ofthe United States, residing at Rochester, in the county ofBeaver and State of Pennsylvania, have invented certain new and usefulImprovements in Apparatus for Elevating Liquid, of which the followingis a specification.

My invention consists of an improved apparatus for elevating liquid froma main tank or reservoir and delivering it through a pump-controlledholder into a vending tank or reservoir, at any desired level or anydesired location, and has in view to provide means for conveying apractically continuous stream by utilization of atmospheric pressure.

The apparatus comprises a pair of vessels into which the liquid iselevated alternately and from one of which it is delivered while ciatedmechanlsm.

One preferred construction is illustrated in the accompanying drawings,in which:

Fig. 2 is a similar vlew 1n side elevation.

Fig. 3 IS an enlarged sectional view of the upper portion of thereceiving vessels,

illustrating the float-controlled operating mechanism.

Fig. 4 is a plan view of the construction shown in Fig. 3.

Fig. 5 is a further enlarged sectional detail vview of thefloat-actuated controlling valve and the surrounding construction.

Fig. 6 is a similar view showing the means for opening the check valvein the feed line to emit return of excess liquid to the main ta I Fig. 7is a detail .view illustrating the main feed pipe provided with aplurality of branches for collecting liquid of difierent grades fromdifierent compartments.

In the drawings, A and B represent two independent vessels as tankswhich are super-imposed at any convenient location above a mainreservoir or tank C, which The apparatus 1 mospheric pressure,

s actuated by normal atoperating to elevate the liquid in a reservoir 0upwardly through a main pipe 2 through one or the other of branchconnections 3, 3, each having an interpos'ed check valve 4 and leadingdirectly by branch pipe 5 to the bottom of one or the other vessel, A orB.

It is designed that the pipe 5 of each vessel shall be used for bothsupplying and withdrawal, for, which purpose, by a T- coupling 6, eachpipe 5 is provided with a laterally arranged pipe 7 and a check valve 8.These branch connections lead by pipe 9 and coupling 10 to a commonoutlet or delivery pipe 11, which is provided with an ordinarygl0bevalve 12 for controlling the flow, pipe 11 being provided with anysuitable terminal as a hose by which the liquid may be'delivered to anydesired point, as a gasolene reservoir of a garage or other dispensingagency.

Each vessel A and B is provided at its central top portion with anupwardly extending cage or conduit, 13, in the lower portion of which isprovided a valve seat '14 adapted to receive a vertically adjustablevalve 15 to seal the opening through condu-it 13 upon rising of a float16. Said float has a limited vertical movement and is raised bytherising liquid in its vertical reservoir, and is in operativeengagement with the suction-controlled valve 15, the float and valvefalling by gravity when the li uid is withdrawn.

loat 16 of chamber A alternates in its action with float 16 of chamberB. Each fioat'is adjustably connected with a vertically is mountedwith-in a conduit 13 which is in communication with the air exhaustingmechanism as hereinafter described.

Valve 15 is secured to the lower end of hollow stem 17 by threaded orother connection and within the stem 17 is mounted the threadedadjustingrod 18. Said rod is provided with a thumb nut terminal 19 at its upperend and extends through the cenmovable hollow stem 17, which stemtubeand its valve are positively actuated by the'rising buoyant movementof float 16 in the particular chamber into which the iqlu-id is beingintroduced, the float and ve in the other chamber correspondinglylowering upon the emptying of said other chamber.

' justed within the clevis up I provide also for the positive un-seatingofthe valve 15 in the other chamber, as B, when the valve in chamber Ais seated, and vice 'versa, by means of a connecting walking beam 23.Said beam is pivotally mounted at 24 on a bracket 25 extending upwardlyfrom the upper portion of the structure and is provided at each end withbifurcated terminals 26. These terminals embrace and engage by means ofpivoting studs 27, a clevis 27 which is threaded or otherwise secured tothe tube 17, as shown in Fig. 5.

By this means the tube is free to be ador down and in connection withadjusting stem 18, the arts may be exactly set to position and witrelation to the walking beam to effect their desired operation, as willbe readily under stood.

It will also be understood that during the exhaustion of the air fromone or the other chamber A or B, it is necessary to seal the chamberagainst entrance of atmospheric air to insure the suction efl'ect of thepartial vacuum created within the chamber and for such purpose eachchamber is provlded with an air inlet valve cage or casing 28 and avalve seat 29, coiiperating with which is an air inlet valve portion ofeach chamber.

Valve 30 is connected by stem 31 and link 32 with walking beam 23 bypivot 33, the

30, at the upper connection between the link 32 and valve 30 beingloose, as by slot 34. By this means,

when valve 15 is lowered to open the suction conduit to the emptychamber and into which liquid is about to be'introduced, the connectionwith the atmosphere will be cut oif.

On the contrary, when valve 15 is closed, Sealing the suction, air inletvalve 30 will be simultaneously raised, allowing entrance of atmosphericair and equalizing the pressure to permit the contents of thatparticular chamber .to flow by avity throu h the one of the conduits 9to t e polnt of co lection or storage. These two conduits lead into thecommon outlet conduit 11 as shown in'Figs. 1 and 2.

For the purpose of exhausting the air from each chamber alternately asdescribed,

and creating the desired partial vacuum therein, each casing 13 isinsuction communication with an air pump 35 by branch pipes 36 and pipe37, preferably provided with a vacuum gage 38. Pump 35 is driven by anysuitable means, as a belt and pulley 39, and operates to effectcontinuous exhaust of air by pipes 36 from .one' chamber or the other,alternately.

As stated, supply pipe 2 by branches 3, is

in direct communication through couplings 6 and pipes 5 with the lowerend of each chamber A and B, and said pipes 5,.oper ating as inlet andoutlet pipes alternately, return the liquid by gravity todelivery pipe11 through check valve 8, check valve 4 being seated against return ofthe liquid downwardly through pipe 3. 1

When at any time 1t is desired to return the contents of either chamberA or B'to the main reservoir 0- without delivery through ipe 11,globe-valve 12 is closed and check valve 4 is positively opened'for suchreturn flow. This lation of adjusting stem 40, mounted within the pipe 3and extending downwardly beoperation is by manipu-,

yond coupling 41 and through a stulfing box and gland 42 thereof andhaving a thumb nut or other terminal 43.

' The stufiing box and gland may be used to provide suflicient frictionfor stem 40 to hold it where set, and the stem may be thrust .upwm' d lytgppen the valve element 4 of check valve 4 to effect such withdrawal.Lowering of stem 40 will leave thecheck valve in its normal condition"of operation When it is desired to use the apparatus for the purpose ofdelivering quantities of liquid of different kinds, or difi'erentgravity, as in the case of gasolene, the main supply "pipe 2 is providedwith a plurality of branch connections 2 each having a controllingglobe-valve 2 as clearlyv shown in Fig. 7. By this constructiontheparticular branch 2 which is in communication with the desiredliquid, as in the case of a compartment tank wagon or the like, isopened by valve 2, the other several valves being closed, so that thecompartment of the particular liquid desired is thus placed incommunication with the machine.
